の量を電気的に制御する関係にある。The dielectric support substrate 2 has a groove 5 in which the liquid ink 4 that accommodates the first electrode 3 can move. A porous body 1 having a wide expanse is installed and joined, and a second electrode 6 is positioned on the opposite side of the porous body 1 to the first electrode 3,
While supplying and impregnating the liquid ink 4, the first and second
Signal voltage between electrodes 3 and 6■8. ■Please tell me oIf,
Liquid ink 4 is applied to the porous body 1 and the dielectric support substrate 2.
The liquid ink 4 is moved through the groove 5 by electroosmosis, and the liquid ink 4 is transferred to the tip 1+1117 of the first electrode 3.
This relationship involves electrically controlling the amount of
まだ溝部５の後端部側は、液状インク４の逆流を防止す
るために、封着剤によって封止される。The rear end side of the groove 5 is still sealed with a sealant to prevent the liquid ink 4 from flowing back.

ていることか記録解像度の点から好ましい。Signal voltages to be recorded V, -V. In the groove 5 that accommodates the first electrode 3 to which Y is applied, the liquid ink 4 is concentrated in the groove S and is force-fed toward the tip 7 of the first electrode 3 as shown by an arrow 11. If the surface of the dielectric substrate 2 is also selected to be electroosmotic in the negative potential direction, the arrow 12 (■.ff and vs-■
. Due to the focusing effect of the liquid ink, the liquid ink is transferred in a dotted manner from the ff side to the s=on side. In this way, the surface 13 between the grooves 6 in which the first electrode 3 is accommodated
That is, the surface of the dielectric support substrate 2 is preferable from the viewpoint of recording resolution because it has electroosmotic property.
以」二述べたことを考慮して従来この種のインク記録ヘ

段としては、硼珪酸ガラス面上に例えば、Ｃｒ等の保護
膜を所望のパターンに形成した後、フッ酸系エツチング
液によりエツチングされ形成される。In consideration of the above, in conventional ink recording heads of this type, borosilicate glass, for example, is used as the dielectric support substrate 2 having good electroosmotic properties, and borosilicate glass is used as the means for forming the grooves 6. A protective film made of, for example, Cr is formed on a glass surface in a desired pattern, and then etched with a hydrofluoric acid etching solution.
しかし、この方法により形成された溝部５の溝底部及び
溝側壁は、その性質上、す９ガラス状。However, the groove bottom and groove side walls of the groove 5 formed by this method are glass-like in nature.
凹凸状態となる。また溝部５を深くすればする程この状
態は顕著に現われる。The surface becomes uneven. Moreover, the deeper the groove portion 5 is, the more this condition appears.

インク量を電気的に制御する関係にあるインク記録ヘッ
ドにおいては、インクの移動を防げる力が増えることと
なシインク記録速度の低下を招く。This is true in an ink recording head in which the liquid ink 4 is moved through the groove 5 that accommodates the first electrode 3, and the amount of liquid ink on the tip side of the first electrode 3 is electrically controlled. This increases the force that prevents the ink from moving, resulting in a decrease in the ink recording speed.

The groove portion 22 is formed by hardening. This groove 2
2 is, for example, 11111! depending on the desired recording resolution. The density is 93 to 8, the width is 50 to 70 μm, the depth is 20 to 50

The metal mask 25 is then removed (FIG. 2C).
. The bottom and side walls inside the groove 22 created by the above method have a mirror-like state on the surface of the support substrate 20 and the smoothness of the organic film 24, so they can be easily accommodated and have less unevenness! ! A groove 22 in which one electrode 26 is accommodated is formed (FIG. 2D).

By selectively depositing by on-set printing etc.
It is possible to form grooves in which liquid ink can move, but compared to grooves formed by conventional etching of borosilicate glass with a hydrofluoric acid-based etching solution, it is possible to form grooves with extremely few irregularities, and the liquid ink can move easily. It becomes easier to move, and the ink recording speed can be improved.

改善できる。Further, if a printing method is used to form the grooves as in this embodiment, the depth of the grooves to be formed can be controlled in any manner. This means that, unlike conventional glass etching, where grooves are formed by etching equally in both the width and depth directions, the grooves are sufficient even at a certain limited pitch between the first electrodes. The recording depth can be increased and the recording density can be improved.

同様の溝部を形成できる。In the embodiment, borosilicate glass is used as the support substrate, but it may also be a quartz substrate or a ceramic substrate such as Ag2O3. Further, in this example, an organic film was described as a material having electroosmosis, but even for materials that require high temperature firing, such as glazed glass, a quartz substrate, a ceramic substrate, etc. can be used as a supporting substrate. A similar groove can be formed by performing partial glazing by screen printing or the like.
